Vorax biofertilizer on off-season maize

The search for more sustainable agriculture has stimulated interest in organic fertilizers. The rising costs of chemical fertilizers and the many benefits identified by the use of biofertilizers have motivated this trend. However, there are many options on the market and assessing the impact of each on yield and crop development is therefore a key aspect in making the best choice. Vorax® Biostimulant is composed of glutamic acid, a source of carbohydrate absorbed by the plant. Therefore, the aim of this work was to evaluate the use of this biostimulant, extracted from Corynebacterium glutamicum, on corn for the off-season. Two experiments were carried out using Vorax® biofertilizer in different combinations of dose, number of applications and phenological stages in a randomized block design with four replications. It was found that when Vorax® is applied at V8 and at lower doses, with a maximum of two applications, there is a (non-significant) gain in yield and ear weight.
